The first break-in happened at Antiques on Elm about 3:20 a.m. Police said the burglar threw a rock through the door, shattering glass and triggering an alarm. A glass display case was also shattered.

"It's still unclear exactly what was taken, but the display case did contain coins and silverware and other assorted items to that effect," said Lt. Maureen Tessier.

The store owners were too upset to talk on camera. Surveillance video showed the burglar as a white man, about 6 feet tall with an average build, wearing a green jacket, gray pants and a black knit hat.

Three hours later, there were two more break-ins on Elm Street. One at the Midtown Cafe was also caught on video.

"When they arrived there, they discovered that someone was able to pry open the exterior doors into a common area that's shared by several businesses," Tessier said. "Once inside that area, they were able to pry open a security gate that allowed them access into the Midtown Cafe."

Surveillance video shows that the burglar pried open a cash register and made off with cash. It also showed the burglar leaving.

"They could actually see the suspect leaving that first business and walking down Elm Street toward the second business that was discovered to be burglarized as well," Tessier said.

The next business hit was Granite State Candy Shop, which also had its cash register pried open and cash removed.

So far, police are not linking the burglaries at Midtown Cafe and Granite State Candy Shop to the one at Antiques on Elm.

"We're still reviewing the surveillance video from Antiques on Elm," Tessier said. "It appears that the individual has somewhat of a different description than the first individual, so we're not able to link those at this point."

The store owners said that even though their businesses were compromised, they have security measure in place that will help police catch those involved.
